When it comes to air filtration systems, home and business owners are increasingly concerned about the quality of air they breathe. While MERV 13 and HEPA filters both remove particles from the air, they work in different ways. MERV 13 filters are designed to remove particles larger than 0 or 30 microns, while HEPA filters are designed to remove particles smaller than 0.30 microns. The Centers for Disease Control and Prevention (CDC) recommends using an air purifier with a HEPA filter for optimal air quality.
HEPA (high-efficiency particulate air) filters are a special type of filter used in hospital operating rooms, ICU units, and other areas that must be extremely clean and hygienic. According to the Environmental Protection Agency, “it can theoretically remove at least 99.97% of dust, pollen, mold, bacteria and any particles suspended in the air” with a size of 0.3 microns (µm). HEPA filters are tested and certified to meet a specific particle size of 0.3 microns, while MERV filters are tested by dust spot testing. This means that HEPA filters are at least 50% more effective at removing air particles from a room compared to MERV air filters.
If you used the HEPA test on a 95% ASHRAE air filter, they would achieve an efficiency of approximately 50% with 0.3 micron particles once they were dusted. In addition to hospitals, HEPA filters are found in some vacuum cleaners and portable air purifiers. While HEPA is a separate filter category, any filter with a MERV rating of 17 or higher is considered a HEPA filter. Therefore, HEPA air filters are at least 50% more effective at removing breathable-sized airborne particles than any of the ASHRAE air filters previously available on the market.
If you're looking for the ultimate solution in the world of air filters that far exceeds what a MERV 13 can do, consider investing in a portable air purifier with a HEPA filter. This will ensure that your home or business is equipped with the best possible filtration system. Investing in an air purifier with a HEPA filter is one of the most effective ways to improve indoor air quality and protect your family from harmful airborne particles.
